Abstract The NASA Radiation Belt Storm Probes (RBSP) mission addresses how
populations of high energy charged particles are created, vary, and evolve in space …

Recent analysis of satellite data obtained during the 9 October 2012 geomagnetic storm
identified the development of peaks in electron phase space density, which are compelling …

The HOPE mass spectrometer of the Radiation Belt Storm Probes (RBSP) mission (renamed
the Van Allen Probes) is designed to measure the in situ plasma ion and electron fluxes over …

Strong enhancements of outer Van Allen belt electrons have been shown to have a clear
dependence on solar wind speed and on the duration of southward interplanetary magnetic …

The past decade transformed our observational understanding of energetic particle
